By Bill Galluccio May 28, 2021 The helicopter on NASA's Mars rover Perseverance had a scare during its sixth test flight. The Ingenuity helicopter ran into problems shortly after taking off when a navigation error caused it to lose control while it was 33 feet off the ground. Officials at NASA's Jet Propulsion Laboratory said the issue occurred when a photo taken from an onboard camera failed to register in the craft's navigation system. That caused a chain reaction, as all subsequent images loaded into the system had an inaccurate time stamp. As a result, the helicopter began to tilt back and forth as much as 20 degrees because the navigation systems couldn't identify its location.
